| Abstract: | Growth of Aspergillus niger and glucoamylase production correlated well with the water activity of the substrate (wheat bran plus corn flour) in a solid-state fermentation. Both were maximal at an initial water activity of 0.936. Glycoamylase reached 550 units/g dry substrate after 96 h.The authors are with the Biotechnology Unit, Regional Research Laboratory, CSIR, Trivandrum-695 019, India |
